1. ABERTURA ACIONADA POR PAINPOINT

Are your gold recovery operations constrained by inefficient primary grinding? Tamanho de feed inconsistente, desgaste excessivo do revestimento, and unplanned maintenance on your comminution equipment directly impact your bottom line. Consider these common challenges in gold ore processing:
Alto custo operacional: Frequent replacement of grinding media and mill liners due to abrasive ore results in significant consumable expenses and production halts.
Tamanho de moagem inconsistente: Variable feed material leads to fluctuating particle size output from your primary mill, reducing downstream cyanidation or gravity recovery efficiency.
Tempo de inatividade excessivo: Traditional mill designs require lengthy, laborintensive shutdowns for liner changes and maintenance, costing valuable production time.
Ineficiência Energética: Older milling technology may consume excessive power per ton of ore processed, tornando a energia um dos seus maiores custos incontroláveis.
Limitações de escalabilidade: Rigid mill configurations struggle to adapt to changing ore body characteristics or increased throughput targets without major capital investment.

Sua operação está buscando uma solução robusta, reliable primary grinding solution engineered to reduce cost per ton and maximize gold liberation?

2. VISÃO GERAL DO PRODUTO

The China Stamp Mill for gold mining is a modernized, heavyduty mechanized crushing and grinding apparatus designed for the primary comminution of goldbearing quartz rock and ores. It functions as a core piece of mineral processing equipment, applying repetitive percussive force to reduce runofmine (ROM) minério para um consistente, liberatable size for subsequent concentration processes.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Minério ROM (typically sized below 100mm) is continuously fed into a centralized feed hopper.
2. Percussive Grinding: Uma série de selos pesados ​​levantados mecanicamente (pesos) are released in a controlled cycle, dropping onto the ore bed contained within a durable mortar box.
3. Redução do tamanho das partículas: The repeated impact fractures the ore along natural grain boundaries, efficiently liberating gold particles without excessive overgrinding.
4. Descarga de lama: Ground material is washed through a discharge screen with water, creating a slurry of target particle size that reports to downstream shaking tables, concentradores centrífugos, or leaching circuits.

Escopo de aplicação & Limitações:
Escopo: Ideal for freemilling gold ores where gravity recovery is viable; effective for smalltomedium scale operations (5500 TPD); suitable for remote sites due to robust mechanical design.
Limitações: Less efficient on clayrich or highly weathered ores that cause packing; not a finegrinding solution—typically produces product in the 20100 mesh range; requer abastecimento consistente de água para manuseio de lama.

6. CENÁRIOS DE APLICAÇÃO

Alluvial/Vein Gold Processing Plant Challenge:

A West African operation processing hard rock quartz veins faced high energy costs and rapid wear from their small ball mill circuit. Downstream gravity recovery was inefficient due to poor and inconsistent primary grind.

Solução:

Implementation of two parallel CSM300 China Stamp Mills as the primary grinding stage ahead of existing shaking tables.

Resultados:

Achieved a target grind of 80%65 mesh consistently. Gravity recovery rate improved from ~55% to over 70%. Combined energy and media savings reduced processing cost by an estimated $18/tonne.

Secondary Grinding Circuit Feed Preparation Challenge:

A South American mine using a cyanidation plant required finer feed but their primary jaw crusher produced too many coarse slabs causing bottlenecks in the secondary roller mill.

Solução:

Installation of a single China Stamp Mill as an intermediate crushing/grinding stage between the jaw crusher and the roller mill.

Resultados:

The stamp mill effectively broke down coarse slabs into granular feed ideal for the roller mill. This balanced the load across the circuit, increasing overall plant throughput by approximately 22%.
